We present data on cognitive, adaptive, and autism severity measures from four time points (pre- and post-EIBI and two follow-up points) for a sample of 21 youth, currently aged 16 years on average (range = 13-20) who received EIBI as young children and who have been out of EIBI for a mean of 10 years (range = 8.5-14). Results show heterogeneous outcomes and a general pattern of stability since the end of EIBI, suggesting gains made in EIBI are maintained %K EIBI %K early intensive behavioral intervention %K long-term effectiveness %K maintenance %U https://journals.sagepub.com/doi/full/10.1177/0145445517746916
